To create an all-inclusive, lifelong learning environment, it is important to build up an information society. In order to carry the mission of a community information resource center, the public library needs to provide its readers with efficient internet and information services through opportunity development, organization management and information integration. With the advancement of information science, it’s more and more popular for libraries to provide customized information services. Under the supervision of Library Director, Dr. Tseng, TPL has made distinguished progress in information services, including the change of the SIRSI System, Household Prompt Book Delivery Service, Real Time System’s Instant Reference Service, Mobile Phone SMS Notifying Service, and My Librarian Reference Service. Below, this study will discuss my visit of libraries in the United States and the new service trends from the public libraries there to bring new insights into development of more efficient and convenient library information services.
